zero flux boundary for diffusion scalar
Hi
Do you know how to set a zero flux boundary for an scalar that is only solved by diffusion. I have tried to use walls and baffles defining a zero flux boundary for this scalar, but it does not seem to stop the scalar from flowing through it. This is a special case, because I have defined other 'normal' scalars (convection & diffusion) that should be able to cross this boundary, but there is one scalar solved only by diffusion that should not cross this point. I would appreciate any suggestions, Many thanks, CM |

Hi
It is me again, sorry I forgot to add something, in case you would like to define a zero flux boundary subroutine, how would you code it? Kind regards, CM |
